Switchboard series

KWTThe lithium battery power distribution integrated board connector is referred to as the power distribution board. The lithium battery power distribution integrated board connector is mainly used for the integrated board connector for the high-speed operation of the high-speed running EMU series with the lithium battery station.

The connector pole of the lithium battery integrated board has the characteristics of large overload current, and the product has good insulation performance, high pressure resistance, fast heat dissipation, large airtight pressure bearing, and strong mechanical bonding strength, which meets the requirements of lithium battery power output connectors. Lithium battery integrated board connector jacket base adopts alloy aluminum6061, The electric conductor pole adopts oxygen-free copperT2, The insulating material adopts glass and ceramics, and through the co-sealing sintering process engineering, the glass ring jacket layer and the electric conductor pole, the ceramic pressure ring and the outer jacket base are combined into an integrated structure. It satisfies the structural strength, compressive strength, insulation, air tightness, high pressure resistance, and fast heat dissipation characteristics of the lithium battery integrated board connector.
